After my first form with your help, I realized the power of PDF files.

In the table below, I wish that when we return 0, 1 or 2 in the box TVA
TOTAL HT that starts automatically in the MONTANT HT box of the table below were the results for each line adds added as in the example below. My Form

Bonjour à tous.

Désolé pour mon anglais, je me sers de Google pour traduire du français vers l’anglais.

Après avoir fait mon premier formulaire avec votre aide, je me suis rendu compte de la puissance des fichiers PDF.

Je viens vers vous aujourd’hui pour la conception d’un script complexe un peu spéciale.

Dans le tableau ci-dessous, je voudrais que lorsque l’on rentre 0, 1 ou 2 dans la case TVA,

Que le montant TOTAL HT se mette automatiquement dans la case MONTANT HT du tableau du dessous été que les résultats s’additionne pour chaque lignes ajoutées comme dans l’exemple ci-dessous. Mon Formulaire

Hi ValdoFR,

It can be done and with a number of approaches.

Basically you will need to set up a loop, to work through the rows and sum the relevant total.

Here is an example:*wyOS7sxGw. It is not exactly what you are after, but it shows the principle.

For example this SHOULD work in the calculate event of the first total MONTAN HT field:

var nRows = Table1._Row1.count;

this.rawValue = 0; // reset MONTAN HT total

for (var i=0; i<nRow; i++)


     var targetRow = xfa.resolveNode("Table1.Row1[" + i + "]");

     if (targetRow.TVA.rawValue == 0)


          this.rawValue = this.rawValue + targetRow.HT.rawValue;



You will need to insert your object references.

Good luck,
